Non-Verbal Communication

I was pointed at an interesting paper on
email
and non-verbal communication [PDF] which tries to explain, through some
experiments, why people can't communicate as well as they expect to be able
to over email and other non-verbal communication methods.

It's an interesting paper though it sort of scares me given that I work
from home and basically only interact with my colleagues and friends over
IRC, email and occasional phone calls. I'm sure I've seen things go awry
due to the sorts of miscommunication that only seems to happen when you
don't actually speak to someone. I'll have to try to ring people more.
